  Official Ruling
  Because Alpha Guard appears only in Un- games, you may run into situations where cards that would normally have the same name—for example, an English-language Forest and a German-language Forest—now have different names. In Un- games, the name printed on the card is that card’s name (unless modified by stickers or other effects). Thus, if you were to choose F for Alpha Guard, you would be able to untap a Forest, but you would not be able to untap a Wald, Forest’s German equivalent.
